The short answer
Start by naming your role. A helper with no document can organise everything but sign nothing; an agent under a durable power of attorney can sign the listing, contract, exchange agreement, identification and closing papers in your parent's name; a successor trustee of your parent's revocable trust signs as trustee once the trust's own terms make you the acting trustee. Your parent stays the taxpayer in every case, so the exchange and the eventual step-up are theirs. The replacement that suits a parent in their eighties is almost always an all-cash DST interest, because it carries no loan, needs no landlord and can be subscribed by an agent or trustee. This page covers the document rules; the dementia guide covers capacity itself and is not repeated here.
At a glance
| Durable language | Florida requires words that the power is not terminated by the principal's subsequent incapacity, or similar words |
|---|---|
| What a third party may ask for | An agent's affidavit, an English translation and an opinion of counsel under Florida section 709.2119 |
| Acceptance deadline | A reasonable time; four business days is presumed reasonable for a financial institution or broker-dealer |
| Powers needing initials | Creating a trust, making gifts, changing survivorship or beneficiary designations: each must be separately signed or initialled |
| Suspension trap | Filing a petition to determine the parent's incapacity suspends the power until the petition is resolved or the court authorises the agent |
| Power ends at death | An open exchange then passes to the personal representative or successor trustee |
| Agent cannot be the intermediary | An agent of the taxpayer is a disqualified person under Reg. section 1.1031(k)-1 |
Three roles, three signatures: helper, agent and trustee
Most adult children start as helpers: they find the broker, read the offers and talk to the intermediary, while the parent signs. That works as long as the parent can sign every document from the listing to the replacement subscription, and the elderly parent guide covers how to weigh the sale itself at different ages. The moment the parent cannot attend a closing, sign an identification letter by day 45 or complete a subscription booklet, the helper needs a legal role.
An agent under a durable power of attorney signs in the parent's name. The power of attorney answer confirms an agent can sign the exchange documents and that the parent remains the taxpayer. What that page does not do is walk through what the document must say and what the people across the table are allowed to demand, which is the subject of this one.
A successor trustee signs when the rental sits in the parent's revocable trust and the trust instrument says the successor acts on the grantor's incapacity, usually on a physician's letter or a defined event. The trust is disregarded for tax while the parent lives, so the trustee's exchange is still the parent's, and the trust-owned exchange page covers titling the replacement in the trust.
What the power must say, using Florida's statute as the model many closing tables follow
Florida's power of attorney act is a useful template because it spells out what everyone in the chain may ask for. Under section 709.2104 a power is durable only if it contains the words that it is not terminated by the principal's subsequent incapacity, or similar words showing that intent. A power without that language dies the day your parent loses capacity, which is often the day you need it most.
Section 709.2202 lists powers an agent may exercise only if the principal signed or initialled next to each one: creating a trust, amending or revoking one, making gifts, creating or changing survivorship rights and changing beneficiary designations. Selling the rental and buying a replacement is ordinary authority; moving the replacement into a newly created trust, or gifting part of the proceeds to grandchildren, is not, and gifts are capped at the annual exclusion unless the document says otherwise.
The statute also says when the power stops. Under section 709.2109 a power terminates at the principal's death, and if anyone files a petition to determine the principal's incapacity the agent's authority is suspended until the petition is dismissed or the court authorises the agent to act. A sibling who files that petition in the middle of a 45-day identification period freezes the exchange; the agent can ask the court for emergency permission, but the clock does not wait.
The title company, intermediary and broker-dealer each get to check you, and the law tells them how
Expect three reviews. The title company must be satisfied the deed is validly signed; the qualified intermediary must be satisfied the exchange agreement binds the taxpayer; the broker-dealer placing a DST interest must be satisfied the subscription is the investor's act. Section 709.2119 lets a third person who accepts a power in good faith rely on it, and lets them require an affidavit from the agent stating where the principal is domiciled, that the principal is not deceased and that the power has not been revoked or suspended, plus a certified English translation and an opinion of counsel on a stated legal question.
Section 709.2120 sets their deadline: accept or reject within a reasonable time, with four business days presumed reasonable for a financial institution or broker-dealer, and any rejection stated in writing with reasons. They may refuse if they know the power is terminated or suspended, if they asked for the affidavit or opinion and the agent refused, or if they believe in good faith that the power is invalid. Deliver the affidavit with the power on day one and most of these objections never arise.
Two rules sit outside the statute. The agent cannot also be the intermediary: an agent of the taxpayer is a disqualified person under Reg. section 1.1031(k)-1, so pick an independent intermediary. And the broker-dealer is required by FINRA Rule 4512 to make reasonable efforts to obtain a trusted contact person for the account, whom it may call to confirm the identity of any holder of a power of attorney or to address possible financial exploitation; being named there, in addition to holding the power, removes a layer of delay.
Hypothetical: a daughter's 180 days with a $700,000 rental and a power that was rejected on day ten
Round numbers, hypothetical: a father of 84 owns a $700,000 rental with a $150,000 basis. His daughter holds a power of attorney signed in 2009. The sale closes on March 1. On March 10 the intermediary's counsel rejects the power in writing: it lacks durable language and the father, after a stroke, can no longer sign a new one. The daughter's options are a petition for guardianship, which suspends nothing because the old power was never durable, or an existing revocable trust if one holds title. Neither is quick, and day 45 is April 15.
Had the power contained the durable words and had she delivered the section 709.2119 affidavit with it, the review would have ended within days. She would have identified two all-cash DST interests on April 10 and closed both in May, well inside day 180, with the father as the investor, the daughter signing as agent, and the deferred $550,000 of gain still inside property that will take a date-of-death basis under section 1014.
The lesson is sequencing. Have an elder-law attorney read the power before the listing agreement is signed, while the parent can still fix it; send the power, the affidavit and the trusted-contact form to the intermediary and the broker-dealer before the sale contract is signed; and only then start the clock. Run the gain and the state tax with the parent's CPA at the same time.
Why the replacement is an all-cash DST, and the two things it costs the family
A parent in their eighties should not be a borrower, a landlord or a party to a construction loan. An all-cash DST interest has no loan to qualify for, no management to oversee and closes on subscription documents an agent or trustee can sign; at death it passes by percentage to the heirs, who can each keep, sell or exchange their share. The page on DSTs for owners over 70 covers the income and estate side.
The costs are control and liquidity. The trustee decides when the property sells, distributions can be reduced or stopped, there is no market to sell the interest into, and principal can be lost. A family that wants to keep the sale decision in its own hands can look at a whole property through a direct title security, but then somebody has to manage it, and that somebody is usually the child reading this page.
- Read the power for durable language and for initialled special powers before anything is listed.
- Prepare the agent's affidavit under section 709.2119 and attach it to every copy of the power you send out.
- Choose an intermediary who is not you, your sibling or the family's attorney or accountant.
- Ask the broker-dealer for its trusted-contact form and have the parent name you on it while they can.
Related questions
My power of attorney is from another state. Will a Florida or Arizona closing accept it?
Usually a power valid where it was signed is honoured, but the third party may still ask for an affidavit, a translation or an opinion of counsel before accepting it. Send those with the power rather than waiting to be asked.
Can I sign the 45-day identification letter as agent?
Yes, if the power covers real property and contracts and is still in force. Sign it in the parent's name by you as agent, and deliver it to the intermediary before midnight on day 45.
What if my brother files for guardianship during the exchange?
Under Florida's statute the agent's authority is suspended while the petition is pending, unless the court authorises specific acts. The 45-day and 180-day deadlines do not pause, so ask the court for emergency authority at once.
Can I put the replacement in my own name to keep things simple?
No. The taxpayer who sold must acquire the replacement, so it goes in the parent's name or the parent's revocable trust. Title in your name ends the exchange and triggers the parent's tax.
Who signs the DST subscription for my parent?
You can, as agent or as trustee, if the sponsor and broker-dealer accept the power and your affidavit. The parent is the investor and must meet the accredited-investor test; a trusted contact on file speeds the review.
